“…Chemically modified silica gel is an attractive sorbent for the extraction and separation of metal ions and various types of compounds, because the silica support does not swell or shrink as polymer resins and unmodified natural materials do [15]. Moreover, the modified silica has a good thermal stability and high metal removal efficiency [16].…”

“…Supported ionic liquids (SILs) which consist of bulky organic cations combined with inorganic or organic anions have recently been developed as a new adsorbent material. SILs have been successfully used in separation work due to its characteristic cations and anions [10,11]. However, there were relatively few reports on its application as a selective adsorbent in the separation and pre-concentration of certain activity components directly from natural plants.…”

“…In this way a higher efficiency in the removal process of metals ions from aqueous solutions is obtained, because it took the advantages of the chemical functionality that ILs can impart and the properties of the solid support [10], [12]- [17]. Different methods of extractant impregnation onto various solid supports have been published such as: dry method of impregnation, encapsulation, sol-gel method, chemical immobilization [6], [7], [9], [11], [12], [18]- [22]. All these mentioned methods are quite time consuming; therefore an alternative green and economic process involving ultrasonication for the impregnation of the metal extractant was proposed [23], [24].…”

Abstract-The influence of the ultrasonication conditions (time and amplitude of ultrasonication) upon the adsorptive properties of the obtained ionic liquid impregnated material, in the removal process of Cs + ions from aqueous solutions, was studied. In the last years ionic liquids was used for the treatment of waste waters containing radionuclides. In order to minimize the treatment cost and to enhance the treatment efficiency, as an alternative to liquid-liquid extraction processes, the use of ionic liquid impregnated support was proposed as a new concept. In the present paper the ultrasonication was used for the impregnation of 1-Butyl-3-methylimidazolium hexafluorophosphate-[BmimPF6] onto Florisil support. Different physical-chemical analysis (scanning electron microscopy (SEM), energy dispersive XRay analysis (EDX), and FTIR-Fourier transform infrared spectroscopy) was used to characterize the obtained ionic liquid impregnated material. In order to obtain a stable and homogenous impregnation of the solid support surface with the studied ionic liquid which will achieve reproducible results in the Cs + adsorption processes it is not necessary to increase the ultrasonication time, but it should be used higher amplitude. The adsorption performance of the Florisil impregnated with [BmimPF 6 ], using optimum conditions of ultrasonication, was studied as a function of Cs + ions initial concentrations. Adsorption isotherms like Langmuir, Freundlich, Dubinin-Radushkevich (D-R), and Temkin were used to analyze the equilibrium data at different concentrations. The experimental data showed good fit to the Langmuir isotherm, followed by the Temkin and Dubinin-Radushkevich isotherms and then the least fit was obtained with the Freundlich isotherm.
